As was mentioned earlier in this thread by @van\_der\_decken, unfortunately there is a bug in the sketch compiler that causes it to fail to find the library when it is installed under a path that contains this sort of character. The workaround will be to configure Arduino IDE to use a different path to store libraries. I'll provide instructions you can follow to do that: Select File \> Preferences...

Hi @brunozwietisch

What is the name of the two libraries you have installed?

Did you install them using the [Arduino IDE Library Manager](https://docs.arduino.cc/software/ide-v1/tutorials/installing-libraries#using-the-library-manager). or by some other method?

Sorry for the delayed response. I managed to solve the problem by updating the IDE. When @TomGeorge mentioned the version, I decided to check which was the most recent IDE, and mine was an older version.

I'm just starting with Arduino, so I got a bit lost here.
